Blindness Risk: Showering in Contacts

Showering in contact lenses can lead to serious eye infections, including Acanthamoeba keratitis, a condition that caused a Texas woman temporary blindness and necessitated a cornea transplant. Experts emphasize that tap water, even from a shower, is not sterile and can harbor harmful microorganisms like bacteria and parasites. These contaminants can become trapped under contact lenses, increasing the risk of corneal infections, ulcers, and potentially permanent vision loss.

Beyond the risk of infection, wearing contacts in the shower can physically affect the lenses themselves. Soft contact lenses can absorb water, causing them to swell and change shape. This warping can lead to discomfort, blurry vision, and irritation. Water's osmolarity differs from the eye's natural tear film, further distorting the lenses and potentially damaging the eye's surface.

Experts strongly advise against wearing contact lenses in any water, including showers, baths, and swimming pools. If accidental water exposure occurs, contacts should be removed immediately, discarded, and the eyes should be cleaned with a sterile saline solution or artificial tears. Prompt medical consultation with an ophthalmologist is essential if any unusual symptoms like sudden pain, redness, or blurred vision arise after such exposure.
